Every year, in the Islamic month of Rabi’ al-Thani, devotees of Abdul Qadir Gilani gather on the bank of the Ravi, and launch paper boats carrying lighted clay lamps and other symbolic offerings in the river. It’s their way of making a wish, or expressing gratitude after their wishes have been granted. The practice is part of the celebrations of the Sufi saint’s urs (death anniversary), which falls on the 11th of Rabi’ al-Thani, the Gyarwi’n Shareef.
